The chart below doesn't look that impressive. However, if we look at the node counts, things start to look more interesting.

HDS would have us understand that the 2-node config had the "lowest ever published overall response time on Spec.org NFS testing." The 4-node result had "more throughput than [the] VNX8000 that had 500+ SSDs and 8 X-blades" at 607,647 vs 580796 Ops/sec. It also had just 4 file systems versus the VNX 8000's 21.

The HDS 4-node job was also faster than a VNX 5700 using a VG8 gateway and 4 VNX arrays, which scored 497,623 Ops/sec.

The 4-node HUS VM config was faster than the NetApp FAS6240 8-node config (512,677 Ops/sec - not in the chart).
